Image 6: Diagnostic Trouble Codes

When your vehicle's malfunction indicator lamp (MIL) comes on, your vehicle has

stored a code that identifies the problem detected. This code is known as a diagnostic

trouble code (DTC). Diagnostic trouble codes are alphanumeric codes that are used to

identify a problem that is present on any of the systems that are monitored by the on-

board diagnostic system. For more information about DTCs, see the “Diagnostic Trouble

Code Breakdown” section.
